The website's founder Mr King said the woman's description of the animal, especially the eye colour, is consistent with black panthers.

"It was definitely a cat, the way it moved wasn't dog like at all. It had a sinuous grace that gives me goosebumps just thinking about it," the woman said.

"The way it moved was incredible - it seemed to judge my speed and walked across with no hurry."

The big cat researcher said usually only males act in a confident manner.

"The males are the ones who are aware of their size, their strength and are almost arrogant in the way they act."

He said it sounded like the animal was not fazed by the approaching car.

"Those sightings are one in a million in Australia, but they do happen," he said.

He said it is possible the big cat is still in the area.

"A breeding male is always going to be patrolling its territory," he said.

But added its exact location now is the million dollar question.

The former Australia Zoo big cat handler said while areas in Victoria and New South Wales are dominating the reported big cat sightings in Australia, as a Sunshine Coast resident, he'd love to prove their in his own back yard.
